ROKURO KOHARU, OF NEW YORK, N. Y.

SIPI-IQN.

T '0 all whom it may concern:

Be it known that I, Roitrfuo IIOHAR'U, a subject of the Emperor ofJapan, residing in the city, county, and State of New York, have made acertain new and useful Invention in Siphons, of which the following is aspecification.

This invention relates to siphons. I

The object of the invention is to provide a construction of siphondevice which is simple, inexpensive to manufacture, easy to manipulate,adjust and clean and effective in operation, for use in the houshold,hospitals, restaurants, cafes, hotels, laboratories, or the like toseparate liquids from each other.

The invention consists substantially in the construction, combination,location and relative arrangement of parts, all as will be more fullyhereinafter set forth, as shown in the accompanying drawing, and finallypointed out in the appended claims.

In the drawing,Figure l is a view in Vertical sectional elevation of asiphon embodying the principles of my invention, and showing theapplication of the same for use. Fig. 2 is a detail View showing theadjust able support for the siphon. Fig. 3 is a broken detail of aslight modification.

The siphon consists of an enlarged chamber C, having straight angularlyrelated legs D, E, communicating independently and directly therewithand extending therefrom, said legs being of the same internal diameteror area in cross section, but the leg D, which I will call the inlet legis shorter than the leg E, which I will call the discharge leg. Theenlarged chamber C, and the straight angularly arranged legs D, E, aremade in one integral piece, and may be made of any suitable material. Ihave found that glass is a suitable material out of which to make thedevice, though, of course, my invention is not to be limited orrestricted in this respect. The upper portion of the enlargedchamber C,is formed into a neck B, over which tightly engages and fits the nippleof a compressible bulb or ball A.

F, is a bottle, jar or other container for the liquids to be separated,and G is a receiving pan or receptacle for the separated liquid.

H, is an adjustable supporting device for the siphon. This is in theform of an adjustable strap arranged to embrace one of the siphon legsand carrying a bracket to Specification of Letters Patent.

rest on the upperedge of the receptacle in connection with which thedevice is used.

In practice I prefer to terminate the lower end of the inlet leg D, in aplane inclined to to the plane of the surface of the liquid to beseparated, as indicated at J. l have found that a better siphoning andseparating action is attained when this condition is observed.

A siphon device embodying the structure as above set forth is not onlyexceedingly simple and inexpensive, but is: effective in operation, theoperation being as follows: The inlet leg I) immersed into the liquid tobe drawn off or separated, and preferably to the lowermost depth of suchliquid, while the discharge leg is directed over or into the receivingreceptacle. The bulb A is then compressed and then the finger is placedover the lower discharge end of the discharge leg E, so as to tightlyclose the same. The bulb is now released and thereupon the liquid intowhich the leg D has been immersed rises through said leg into thechamber C. By removing the finger from the lower end of the leg E, thisliquid flows out of chamber C, through the leg E, and into the receivingreceptacle G, thus starting the flow of the liquid which flow ismaintained until the bulb A is again compressed, or the liquid to beseparated is exhausted or the siphon. is removed. The inclined lowerface or end surface of the leg D facilitates the starting of the flow.By suitably adjusting the supporting device H, on the leg D, the depthof immersion of said leg in the liquid to be drawn off may be regulated,said de vice, II, also serving to support the siphon.

It may sometimes be desirable to avoid using the finger to close thelower or discharge end of the discharge leg in starting the siphonaction, as, for instance, when said leg is inserted into a deepreceiving receptacle where it is diflicult to reach the discharge end ofsaid leg. In order to avoid this difliculty, I may employ a sleeve K, ofrubber or other suitable material and having an end flap L. This sleeveis slipped over the lower end of leg E and the flap L, nor mallyoperates to close yieldingly against the lower open end of leg E.Whenever the bulb A is compressed the air forced out of the siphonthrough leg E will cause the flap L to open, and when the compressedbulb is released the flap will automatically close. When the flow ofliquid commences the weight thereof imposed on the flap L will causesaid flap to open.

A siphon device as above described, em bodying the straight legs D, E,merging in dependently and directly into the enlarged chamber C, permitsthe device to easily and thoroughly be cleaned by inserting a cleaningbrush and working the same back and forth longitiulinally of said legs.T his is an important matter especially when the de vice is employed. toseparate cream from milk for food purposes. in the use of the device a.perfect and complete separation is effected.

The combined volume of the enlarged chamber C and legs D, E, should bethe same as the volume of the compressible bulb A, to secure the bestresults.

Having now set forth the objects and nature of my invention and a deviceem bodying the principles thereof, what I claim as new and useful, andof my own invention and desire to secure by Letters Patent is,-

1. A siphon comprising an enlarged chamher having straight legs eachcommunicating independently therewith and extending therefrom but formedin one piece therewith, and a compressible bulb associated with saidchamber.

2. A siphon comprising an enlarged chamber having a neck and straightlegs each communicating independently with the chamber and eXtendingtherefrom in angular relation to each other, said chamber, neck and legsbeing formed in one piece, and a conun'essible bulb fitted to said neck.

2: A siphon comprising an enlarged chamber having a neck and straightlegs all formed in one piece said legs communicating indepmidently ofeach other with said cham her, and a compressible bulb fitted to saidchamber neck, the combined volume of said chamber and legs correspondingto the VOlume of said bulb.

at. A siphon comprising an enlarged chamber having a neck and straightlegs all formed in one piece each communicating independently of eachother with said chamher, a con'lpressible bulb fitted to the chamberneck, and a yielding flap applied directly to the open end of one ofsaid legs.

In testimony whereof I have hereunto set my hand in the presence of thesubscribing witnesses, on this 17th day of hilarch A. 1)., 1910.
